Product Details
For the recording solution, the user can choose a recording IC chip or a recording module. The recording and playback IC and the recording module can record and save at will by triggering the REC recording button, and after the recording is completed, trigger the PLAY play button to play the recording, and can realize repeated recording and playback. A voice storage chip (see the schematic diagram in Principles of Recording Chips), which includes two processes, ADC and DAC, both of which are completed by the chip itself, including steps such as voice data collection, analysis, compression, storage, and playback.
